        After examining the difference in the photosynthesis rate of corn according to the planting distance, the distance of 40 × 40 cm showed the lowest rate by 23 days after transplanting (May 31); however, there was no significant difference in the photosynthesis rate due to increased salt tolerance in the plant as time went by. As for the difference in growth features of a plant, the planting distance of 40×40cm showed a growing disorder due to the influence of salt by 23 days after transplantation (May 31); however, there was a desirable growth as time went by. For the difference in the salt content within a plant, the planting distance of 40×40cm tended to be higher than other planting distances, and the K⁺ content is much higher than other kinds of salt after examining the difference in salt absorption. As for the correlation between saline components within a plant, there was a significant negative correlation among K⁺, Ca²⁺, and Na⁺ while there was a significant positive correlation among Mg²⁺, Ca²⁺, and Na⁺. After examining the effectiveness of salt removal from soil according to corn cultivation, the planting distance of 30×30㎝ showed a remarkable decrease by 37 days, compared with 23 days, after transplantation in K⁺ by 28%, Ca²⁺ by 36.6 %, Mg²⁺ by 30.6 %, and Na⁺ by 22.9 %. And the salt content is higher in surface soil than in subsoil.
